To all whom it may concern:

Be it known that I, HANS SCHLER, a subject of the German Emperor, residing at No. 6 I-Iansaplatz, in the city of Hamburg, Germany, have invented a certain new and useful Improvement in DoubleBogies for Railway-Cars and other Vehicles, of which the which carries four wheels, in such manner that the rear wheels of one single-bogie truck and the forward wheels of the 4other bogietruck are located between the front and rear.

wheels of the mating truck.

Said invention is fully shown and described in the following specification, of which theA accompanying drawings form a part, wherein similar letters of reference desi nate like or equivalent parts wherever foun throughout` the several views, and in which- Figure 1 is a side diagrammatic View of a v car of the ordinary well-known double-bogie truck form now in general use. Fig. 2 is a like view of a car provided with my improved double-bogie truck. Fig. 3 is a top plan view of a double-bogie truck of my improved form removed from 'the car. view of a slightly-modiiied form of construction from that shown in Fig. 3; and Fig. 5 is an end view of the construction shown in Fig.

3, while Fig. 6 is a like end'view of the construction shown in Fig. 4.

In the drawings the reference-letters a, represent one single-bo ie truck-frame, and a its mating bogie truc -frame, while the reference-letter b designates the double-bo ie truck-frame joinin the single-bogie truc s together into a dou le-bogie truck.

'shown in Fig. 3 in plan and -in'Fig 5, or over .each other, as represented in Fig. 4 in side Fig. 4 is a side Fig. 2, in contradistinction to Fig. 1, in which 5 the separate bogies are arranged one behind the other. In Fig. 2 the frames of the separate bogie are re resented by curved lines,

because-straight ines would partly overlap and render the drawing unintelligible. The 6 arrangement shown in Fig. 2 enables the dis-- tance lbetween the axles of the separate bogies to be increased in order to minimize the racking movement and the length of the en-` tire kdouble-bogie frame to be decreased to a considerable extent. Compared with the construction shown in Fi 1 the reduction of the length of the doub e-bogie frame according to Fig. 2 hasthe advantage thatthe Y connection'between the vertical axles of the separate bogie-frames is shorter and lighterv and the distance the caroverhangs at each end is reduced. As a consequence vibrations at the car ends are reduced and the limitations of the dimensions heretofore necessary in view of the curves to be passed over is .also rendered less.

The frames of the separate bogies a a can be arranged either behind eac other, as

view and in Fig. 6. As indicated Vin dotted lines in Fig. 3, the frame can be arran ed either inside or outside the wheels. Furt er modifications of the frame can be made by 8 bending the metal.` 4

VVhilel-my invention is, designed and intended more particularly for 4railwayvehicles, the same isnot by any means limited thereto and may withadvantage be used in road-vehicles of various kinds, such as automobiles, &c.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is f 1. A double bogie for railway-cars and other vehicles in which that axle of the single bo ie which is nearest to the main vertical ax e of the double-bogie frame is located between the axles of the other single bogie, substantially as shown `and described.

2. In. a' double bogie for railway-cars, a single-bogie frame located within the wheels at IOO together', in such manner that those Wheels my invention I have signedy iiar'n'e in presald axles of each frame nearest to thgJ center ence of tWo subscribing Witnesses.

oV the double-bogie frame are located etween the iront and rear Wheels and axles of the HANS SCHULER' 5 other bogie-frames, substantially as shown Witnesses:

and described. E, H. L. MUMMENHOFF, In testimony that I claim the foregoing as OTTO W. HELLMRIGH.
